There are four main directions of relieving the oil wells mortars:

  • increasing water-cement ratio
  • aeration of the grouting mortar with air-gas mixtures
  • use of weight light additives [1][2]
  • chemical reaction and air-entraining of components while cementing.

Finely porous foamed ceramic microspheres of the specified size 0.1 to 0.6 mm with a solid and strong shell are used as a lightweight filler.
